Those 60 hypothetical hours of office time are more than the usual day job, which, of course, clocks in on average at about 35 to 40 hours a week.

But it's about the same as a lot of people working menial (or multiple) jobs like driving Uber, where people can put in 80 hours or more every week just to make ends meet in the ridiculously expensive San Francisco Bay Area, where Facebook is based.

In fact, Internet.org was a hot topic, with plenty of questions involving whether it was coming to regions such as Europe and Canada. The answer is that Facebook wants to focus on the developing world, where few people are online, before it starts to really focus on more saturated areas.

And another from Shakira on how Facebook can be used for education in the developing world:

As Facebook takes on a greater and greater role in global communications, it's good to see Zuckerberg take a more active hand in talking to the community. It would just be nice to hear something other than the party line once in a while.
